Hmmmm... never thought of it that way. Always thought of GD as a graphics library, but I guess it makes sense to think of modules for actually displaying the images as being different from modules that create those images in the first place. >> >> On top of that, PDL::IO::GD is actually listed >> under the "Documentation" sub-heading rather than >> under the "Modules" sub-heading.... > > Documentation bugs are bugs.

I filed it in the sf bug tracker, but basically it is the same info as noted above. Nothing more. .. > >> 4. Finally, my question re. using PDL::IO::GD.

I am still at the "how do I make an image from a collection of x,y values" stage. -- Puneet Kishor http://www.punkish.org Carbon Model http://carbonmodel.org Charter Member, Open Source Geospatial Foundation http://www.osgeo.org Science Commons Fellow, http://sciencecommons.org/about/whoweare/kishor Nelson Institute, UW-Madison http://www.nelson.wisc.edu ----------------------------------------------------------------------- Assertions are politics; backing up assertions with evidence is science ======================================================================= _______________________________________________ Perldl mailing list [email protected] http://mailman.jach.hawaii.edu/mailman/listinfo/perldl
